  • COMPare: a prospective cohort study correcting and monitoring 58 misreported trials in real time | Trials | Full Text
    https://trialsjournal.biomedcentral.com/articles/10.1186/s13063-019-3173-2

    Methods

    We identified five high-impact journals endorsing Consolidated Standards of Reporting Trials (CONSORT) (New England Journal of Medicine, The Lancet, Journal of the American Medical Association, British Medical Journal, and Annals of Internal Medicine) and assessed all trials over a six-week period to identify every correctly and incorrectly reported outcome, comparing published reports against published protocols or registry entries, using CONSORT as the gold standard. A correction letter describing all discrepancies was submitted to the journal for all misreported trials, and detailed coding sheets were shared publicly. The proportion of letters published and delay to publication were assessed over 12 months of follow-up. Correspondence received from journals and authors was documented and themes were extracted.

    [...]

    Conclusions

    All five journals were listed as endorsing CONSORT, but all exhibited extensive breaches of this guidance, and most rejected correction letters documenting shortcomings. Readers are likely to be misled by this discrepancy. We discuss the advantages of prospective methodology research sharing all data openly and pro-actively in real time as feedback on critiqued studies. This is the first empirical study of major academic journals’ willingness to publish a cohort of comparable and objective correction letters on misreported high-impact studies. Suggested improvements include changes to correspondence processes at journals, alternatives for indexed post-publication peer review, changes to CONSORT’s mechanisms for enforcement, and novel strategies for research on methods and reporting.

  • Cancer de la prostate : le suivi fait aussi bien que la chirurgie
    http://www.pourquoidocteur.fr/Articles/Question-d-actu/17558-Cancer-de-la-prostate-le-suivi-fait-aussi-bien-que-la-chirurgi

    L’ablation de la prostate n’est pas toujours justifiée lorsqu’un cancer est détecté. L’approche à adopter est régulièrement discutée. Une étude parue en deux volets dans le New England Journal of Medicine pourrait bien trancher ce débat pour de bon. Réalisée par l’université d’Oxford (Royaume-Uni), elle montre qu’entre la chirurgie, la radiothérapie et une surveillance active, aucune différence n’émerge sur la survie. Pourtant, les travaux ont été réalisés pendant une décennie, auprès de 82 429 hommes de 50 à 69 ans.

    • Les conclusions de l’étude du NEJM (acccessible en ligne)

      10-Year Outcomes after Monitoring, Surgery, or Radiotherapy for Localized Prostate Cancer — NEJM
      http://www.nejm.org/doi/full/10.1056/NEJMoa1606220#Top

      CONCLUSIONS
      At a median of 10 years, prostate-cancer–specific mortality was low irrespective of the treatment assigned, with no significant difference among treatments. Surgery and radiotherapy were associated with lower incidences of disease progression and metastases than was active monitoring.

    • Au total (dernier paragraphe de l’article):

      At a median follow-up of 10 years, the ProtecT trial showed that mortality from prostate cancer was low, irrespective of treatment assignment. Prostatectomy and radiotherapy were associated with lower rates of disease progression than active monitoring; however, 44% of the patients who were assigned to active monitoring did not receive radical treatment and avoided side effects.5 Men with newly diagnosed, localized prostate cancer need to consider the critical trade-off between the short-term and long-term effects of radical treatments on urinary, bowel, and sexual function and the higher risks of disease progression with active monitoring, as well as the effects of each of these options on quality of life. Further follow-up of the ProtecT participants with longer-term survival data will be crucial to evaluate this trade-off in order to fully inform decision making for physicians and patients considering PSA testing and treatment options for clinically localized prostate cancer.

    • Une publication antérieure de la même étude permet d’avoir une indication sur la valeur du PSA aux taux retenus comme test de détection d’un cancer, en particulier localisé (versus faux positif)
      http://www.ncbi.nlm.nih.gov/pubmed/25163905?dopt=Abstract

      Of the 8566 men with a PSA concentration of 3·0-19·9 μg/L, 7414 (87%) underwent biopsies. 2896 men were diagnosed with prostate cancer (4% of tested men and 39% of those who had a biopsy), of whom 2417 (83%) had clinically localised disease (mostly T1c, Gleason score 6).

  • How the sugar industry has distorted health science for more than 50 years
    http://www.vox.com/2016/9/12/12864442/jama-sugar-industry-distort-science

    “[...] Is it really true that food companies deliberately set out to manipulate research in their favor? Yes, it is, and the practice continues.” Nestle has been documenting the instances where companies fund nutrition studies that overwhelmingly return favorable results to the industry sponsors.

    “Our research emphasizes that industry-funded science needs to be heavily scrutinized, and not taken at face value,” said Kearns, the lead author on the JAMA paper. “There are so many ways a study can be manipulated — from the questions that are asked, from how the information is analyzed, even to how the conclusions are described in the paper.”

    In this case, the sugar industry involvement in science influenced not only the scientific enterprise but also public-health policy, and potentially, the health of millions of people. Kearns points out that the most recent World Health Organization sugar guidelines focus on reducing consumption because of sugar’s role in obesity and tooth decay — not the heart risk.

  • Smartphone use in the dark linked to temporary blindness in 2 cases
    http://mashable.com/2016/06/23/temporary-blindness-tied-to-smartphones/#wUKUpGc1Ckqw

    In Thursday’s New England Journal of Medicine, doctors detailed the cases of the two women, ages 22 and 40, who experienced “transient smartphone blindness” for months.

    The women complained of recurring episodes of temporary vision loss for up to 15 minutes. They were subjected to variety of medical exams, MRI scans and heart tests. Yet doctors couldn’t find anything wrong with them to explain the problem.

    But minutes after walking into an eye specialist’s office, the mystery was solved.

    “I simply asked them, ’What exactly were you doing when this happened?’” recalled Dr. Gordon Plant of Moorfield’s Eye Hospital in London.

    He explained that both women typically looked at their smartphones with only one eye while resting on their side in bed in the dark — their other eye was covered by the pillow.
    […]
    He said the temporary blindness was ultimately harmless, and easily avoidable, if people stuck to looking at their smartphones with both eyes.

  • The best health care system in the world? Nonsense!
    http://www.publicintegrity.org/2015/06/01/17426/best-health-care-system-world-nonsense

    To understand how foolish we are, let’s consider the war of words that recently erupted between health insurers and drug companies.

    First, though, let’s take a look at a new study that compares how much Americans pay for prescription medication compared to what folks in a few other industrialized countries pay.

    The study, released last week by the Kaiser Permanente Institute for Health Policy, showed that pharmaceutical spending in the U.S. per capita had reached $1,010 in 2012. The next highest spender was Germany at $668 per capita. Australia came in at $558.

    Am I the only one who finds it more than a little upsetting that the Germans spend 66 percent of what we spend for drugs and the Aussies spend just 55 percent?

    As the Kaiser researchers point out, those countries’ citizens get a much better deal on their meds because their federal governments have policies in place to regulate drug prices. And those nations are not alone. Every other country in the developed world has instituted some kind of price control mechanism. Except, of course, the United States.

    Kaiser’s numbers are consistent with those from a 2013 analysis by the 34-member Organization for Economic Cooperation and Development (OECD), which showed that Americans spend 40 percent more on drugs than the next highest spender, Canada.

    As PBS pointed out last year in a report on drug prices around the world, government agencies in other countries set limits on how much they (and their citizens) will pay drug makers for their various products.

    “By contrast,” as PBS further pointed out, “in the U.S., insurers typically accept the price set by the makers for each drug, especially when there is no competition in a therapeutic area, and then cover the cost with high copayments.” (Emphasis mine.)

    PBS nailed it. American insurance companies are essentially powerless when it comes to negotiating prices with Big Pharma, just as they are becoming increasingly powerless in controlling the cost of hospital care and physician services. The way insurers continue to make money is not by doing a good job for their customers but by constantly shifting more of the cost of care to those customers.

    If we were paying close enough attention to what insurers were saying during the health care reform debate, we would have realized that they are, for all practical purposes, impotent when it comes to holding down costs. All we had to do was read between the lines.

    • Free market ideology doesn’t work for health care
      http://www.publicintegrity.org/2015/06/08/17460/free-market-ideology-doesnt-work-health-care

      In my column last week I suggested that one of the reasons Americans tolerate paying so much more for health care than citizens of any other country — and getting less to show for it — is our gullibility. We’ve been far too willing to believe the self-serving propaganda we’ve been fed for decades by health insurers and pharmaceutical companies and every other part of the medical-industrial complex, a term New England Journal of Medicine editor Arnold Relman coined 35 years ago to describe the uniquely American health care system.

      One of the other reasons we tolerate unreasonably high health care costs is gullibility’s close and symbiotic relative: blind adherence to ideology. By this I mean the belief that the free market — the invisible hand Adam Smith wrote about more than two centuries ago and that many Americans hold as a nonnegotiable tenet of faith — can work as well in health care as it can in other sectors of the economy.

      While the free market is alive and well in the world’s other developed countries, leaders in every one of them, including conservatives, decided years ago that health care is different, that letting the unfettered invisible hand work its magic in health care not only doesn’t create the unintended social benefits Smith wrote about, it all too often creates unintended, seemingly intractable, social problems.

  • An open letter for the people in #Gaza
    http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2814%2961044-8/fulltext

    En attendant l’étasunien “New England Journal of Medicine,”

    We denounce the myth propagated by Israel that the aggression is done caring about saving civilian lives and children’s wellbeing.

    Israel’s behaviour has insulted our humanity, intelligence, and dignity as well as our professional ethics and efforts. Even those of us who want to go and help are unable to reach Gaza due to the blockade.

    This “defensive aggression” of unlimited duration, extent, and intensity must be stopped.

    Additionally, should the use of gas be further confirmed, this is unequivocally a war crime for which, before anything else, high sanctions will have to be taken immediately on Israel with cessation of any trade and collaborative agreements with Europe.

    As we write, other massacres and threats to the medical personnel in emergency services and denial of entry for international humanitarian convoys are reported.6 We as scientists and doctors cannot keep silent while this crime against humanity continues. We urge readers not to be silent too.

    Gaza trapped under siege, is being killed by one of the world’s largest and most sophisticated modern military machines. The land is poisoned by weapon debris, with consequences for future generations. If those of us capable of speaking up fail to do so and take a stand against this war crime, we are also complicit in the destruction of the lives and homes of 1·8 million people in Gaza.

    We register with dismay that only 5% of our Israeli academic colleagues signed an appeal to their government to stop the military operation against Gaza. We are tempted to conclude that with the exception of this 5%, the rest of the Israeli academics are complicit in the massacre and destruction of Gaza. We also see the complicity of our countries in Europe and North America in this massacre and the impotence once again of the international institutions and organisations to stop this massacre.

    • Israel–Gaza conflict

      Suivant la « lettre ouverte » publiée par le Lancet, certains collègues l’ont critiqué en l’accusant, au mieux, de « faire de la politique », et au pire d’être « tout simplement antisémite ». Ici une réaction de médecins juifs d’Afrique du Sud,

      We write as Jewish health professionals in South Africa in response to the debate on the war in Gaza.1 Many of the letters have been critical, sometimes viciously so, of The Lancet for airing this debate, labelling it “inappropriate for a peer-reviewed medical journal to publish purely political, inaccurate, and prejudiced pieces”2 and have gone on to equate the original call by Paola Manduca and colleagues1 as “anti-Jewish bigotry, pure and simple”.2

      We disagree and are disturbed at the lack of insight of many of the criticisms that seem to focus on a narrow view of humanitarianism out of touch with current scientific and ethical thinking about the human rights obligations of health professionals. For example, the idea that “Medicine should not take sides”3 and that provision of medical care to Palestinian victims of the war represents a sufficiently ethical response4 is extremely problematic. Even more so is the argument that accuses those who speak out against the consequences of the war for civilians as inciting hate or introducing politics “where there is no place for it”.3

      Remaining neutral in the face of injustice is the hallmark of a lack of ethical engagement typical of docile populations under fascism.5

      More recent understandings of the role of humanitarianism in health (often involving noble and courageous actions) have highlighted the limitations of non-engagement as a moral choice and have argued that apolitical approaches that focus on emergency relief are wholly inadequate.6,7

      As South Africans who witnessed the worst excesses of state brutality under apartheid, we would have failed our professional duties had we not spoken up against ethical and human rights violations committed against civilians by an abusive state.

      We most certainly did not have the opportunity to air such views in our country’s medical journal, which suppressed public statements by concerned health professionals and labelled such appeals for justice and human rights as “political”.8 In its 1997 investigation, the South African Truth and Reconciliation Commission highlighted the abysmal ethical failings of the health professions in challenging apartheid medicine and the violations of human rights. History has proved us correct in our estimation that health workers should not stand by while injustice leads to the death and injury of civilians in a conflict that could be prevented.

      We therefore wish to express our support for your decision to permit a discussion in the columns of The Lancet on the professional, ethical, and human rights implications of the current conflict in Gaza.

      We believe it entirely appropriate that health professionals speak out on matters that are core to our professional values and that The Lancet provides an independent and respected platform for such engagement. Thank you for allowing voices to be expressed that would otherwise be suppressed by prejudice, politics, and a partisan view of the ethical and human rights responsibilities of health professionals.

      All the authors were harassed, victimised, or detained for being anti-apartheid activists. LL, DS, SF, SU, LB-R, and SG signed an open letter calling on South Africa to expel the Israeli ambassador during this current conflict.

  • Our Feel-Good War on Breast Cancer - NYTimes.com
    http://www.nytimes.com/2013/04/28/magazine/our-feel-good-war-on-breast-cancer.html

    In the United States, some researchers credit screening with a death-rate reduction of 15 percent — which holds steady even when screening is reduced to every other year. Gilbert Welch, a professor of medicine at the Dartmouth Institute for Health Policy and Clinical Practice and co-author of last November’s New England Journal of Medicine study of screening-induced overtreatment, estimates that only 3 to 13 percent of women whose cancer was detected by mammograms actually benefited from the test.

    If Welch is right, the test helps between 4,000 and 18,000 women annually. Not an insignificant number, particularly if one of them is you, yet perhaps less than expected given the 138,000 whose cancer has been diagnosed each year through screening. Why didn’t early detection work for more of them? Mammograms, it turns out, are not so great at detecting the most lethal forms of disease — like triple negative — at a treatable phase. Aggressive tumors progress too quickly, often cropping up between mammograms. Even catching them “early,” while they are still small, can be too late: they have already metastasized. That may explain why there has been no decrease in the incidence of metastatic cancer since the introduction of screening.

    At the other end of the spectrum, mammography readily finds tumors that could be equally treatable if found later by a woman or her doctor; it also finds those that are so slow-moving they might never metastasize. As improbable as it sounds, studies have suggested that about a quarter of screening-detected cancers might have gone away on their own. For an individual woman in her 50s, then, annual mammograms may catch breast cancer, but they reduce the risk of dying of the disease over the next 10 years by only .07 percent — from .53 percent to .46 percent. Reductions for women in their 40s are even smaller, from .35 percent to .3 percent.

    If screening’s benefits have been overstated, its potential harms are little discussed. According to a survey of randomized clinical trials involving 600,000 women around the world, for every 2,000 women screened annually over 10 years, one life is prolonged but 10 healthy women are given diagnoses of breast cancer and unnecessarily treated, often with therapies that themselves have life-threatening side effects.
